Subject: atten-pps3xxx: Make serial write call block.
X-Git-Tag: libsigrok-0.4.0~974
X-Git-Url: https://sigrok.org/gitweb/?a=commitdiff_plain;h=c3116bc3115fb9f759fc9f4cb38f19746e533877;p=libsigrok.git

atten-pps3xxx: Make serial write call block.

This call is executed from an event handler and was previously nonblocking,
but has no partial write handling. It sends a short packet so should be OK
to block, most likely the output buffer will be empty anyway.
